CALENDAR-CLOCK.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed July 12, 1917. Serial No. 180,209.

To all whom-it may concern:

Be it known that I GAETANO F RICANO; a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Calendar-Clocks, of which thefollowing is a specification.

This invention relates to clocks of the kind adapted to indicate the day and month of the year in addition to the time of day.

The objects of the invention are to pro duce a clock provided with a mechanism of improved construction for transmitting motion from the clock mechanism to the calendar mechanism; also to provide means of improved construction for preventing the winding of, the clock from interfering with the calendar mechanism; also to provide a mechanism of improved construction for transferring motion from the day wheel to the month wheel of the clock; also to provide mechanism of improved construction for moving the day wheel to its starting position on the first of each month; also to provide means of improved construction to prevent rebound when the day wheel moves into its starting position; also to improve the construction of devices of this kind in other respects hereinafter specified.

In the accompanying drawings Figure l is a face view of the dial of a calendar clock embodying the invention.

Fig. 2 is a face view of the day indicator detached from the clock.

The calendar mechanism of the clock may be applied to a clock mechanism of any suitable construction, that shown comprising the usual frame on which the gear train 26 of the clock mechanism is suitably mounted. The gear train shown may be actuated by any suitable means, such for example as a spring 27 secured on a winding shaft 28 having the usual squared end 29 adapted to receive the clock winding key. The winding mechanism is provided with the usual ratchet wheel 30 and pawl 31 which permit the winding shaft to be turned in a direction for winding without interfering with the gear train 26. The clock mechanism 26 is connected with an hour hand 32 and a minute hand 33 adapted to move over the usual clock dial 3 1. Any other clock mechanism may be employed for imparting movement to the calendar mechanism.

Movement may be imparted to the calendar mechanism from any desired part of the clock mechanism. In the construction shown the calendar mechanism derives its movement from the winding shaft 28 on which a driving gear 35 is mounted to rotate relatively to the winding shaft 28. The driving gear 35 of the calendar mechanism is actuated by means of a driving member 36 rigidly mounted on the winding shaft 28, preferably on the squared end 29 thereof, and havin arms 3T extending between the spokes of the driving gear 85 so that the gear 35'will be driven by therotation of the winding shaft but will have a limited movement on this shaft independently of the driving member 36; The driving gear 35 meshes. with a pinion $0 of a day wheel actuating mechanism mounted on a pin or post ll'Vr-igidly secured onthe frame 25 of the clock mechanism.

tooth 46 rotatably mounted on a pin e7 se-' cured on the plate l5 of the day wheel "actuating mechanism. the construction shown is pivotally mounted on a sleeve 48 pivoted onthe pin a? and a plate or holder l9 for the spring tooth is secured on thesleeve 48 and is provided with a shoulder or stop 50 against which the spring tooth is yieldingly held by means of a spring 51. Rotation is imparted to the sleeve i8 by means of a Geneva movement including a notched or toothed wheel or disk F2 rigidly securedon the sleeve 48 and having a plurality of teeth or projections, the outer faces 53 of which are curvedand which are spaced apart-forming slots or notches in which a tooth 55 on a disk 56 mounted on the post 41 is adapted to engage. The curvature of the outer face of the disk 52 issubstantially the same as the curvature of the disk 56 so that the toothed wheel 52 will be rotated through the distance of onevtooth'orprojection'for each revolution of the wheel or plate 45 about its pivot ll, qThe Geneva wheel 52 is provided with five; projections so that the spring tooth t6 connected-therewith is rotated once about the pivot $7 for every five revolutions of the pivot e7 about the pivot 41. The spring tooth 46 is so positioned on the wheel or plate -15 that it will only actuate the day wheel 4-2 when the tooth extends "substantia-lly'radial with regard to the pivot 41 as shown in Fig. 5 and since the sprino' tooth only occupies this position once m fivetimes the day wheel 4Q will be actuated once per day. lVhen the clock is being wound the driving gear 35rotates with the winding shaft 28 of the clock mechanism and rotates the wheel or plate45 and the mechanism mount The pinion l0 and the gear 35 111 the construction shown are In order to ac- The spring toothlG in ed thereon in a reversedirection, causing the spring too-thto swing relatively to the v sleeve-4B against'the action of the spring 51 winding shaftQS is permitted to move forwardly through a short distance during the winding of the clock, as will frequently occur before the pawl the winding mechanism moves into engagement with a tooth ofthe ratchet wheel 30.

The day wheel shown in the drawings is pivoted to turn about the axis on which the day and hour hands revolve and is provided at its pcripheryewith ratchet teeth adapted to be engagedby the spring tooth 46 of the day wheel actuating mechanism and with an arm 60 suitably connected to turn with the day wheel i2 and carrying an annular card or indicator 61 on which the days of the month are indicated, the card being so r positioned that the daysof the month will be visible one at a time through a hole or opening (32 in the dial of the clock. The day wheel is connected with one end of a coilspring- 63, the other end of which is connected to an arm or fixed part 6d of the frame 25 of the clock mechanism, so that the spring 63 will tend to hold the day wheel in its starting position in which the numeral 1 of the indicator 61 will be visible through the opening 62 in thedial. The day wheel is moved forwardly through the distance of one tooth at a time by the spring finger 46 against the action of the spring 63 and the day wheel is held against returning to its starting position by means of a pawl or de'tent 6T pivoted at 68 on the frame of the clock mechanism and held bv means ofa spring 69 ina position in which a tooth '70 of the pawl will engage in the ratchet teeth of theday wheel l2.

The means for indicating the months on the clock and for returning the day wheel to its starting position atthe end of each month are preferably constructed as fol lows:- ,7 J r The day wheel provided with four pins or projecting portions 75, 7 6, .77 and '78 which are adapted to. engage with teeth or projectionsformed on a month wheel pivotally mounted on a pin or shaft 81 suitably pivoted in the clock frame vThe month wheel in the construction shown is provided 'Wlllll a hollow hub portion 83, F 1g. 8, which gear or toothed wheel 85, the projection 87 and pin 88 being so positioned as to form a stop for the month wheel, against which the projection 87 thereof is held by the spring 81. The gear or toothed wheel 85 of the month indicating mechanism is held against movement by means of a tooth or part 90 formed on the detent 67 and which is adapted to engage between the teeth of the gear or toothed wheel 85.

The month wheel 80 is provided with a plurality of teeth or projections which are arranged to engage with one or another of the pins 75, 76, 77, T8 of the day wheel d2, the pin '78 being adapted to engage a projection on the month wheel 80 corresponding to a 28-day month and the pins 77, 76 and 75 being adapted to engage projections on the month wheel corresponding respectively to a twenty-nine a t'hirt and a thirtv-one da month. In the construction shown for this purpose the pins are made of gradually in creasing length, the pin 78 being the shortest and the pin 75 being the longest. The shortest pin 78 engages teeth 92 of the month wheel which extend toward the day wheel. A tooth 93 on the month wheel extends toward the day wheel to a. less extent than the teeth 92 so that the pin 77 will engage this tooth but the pin 78 will pass the projection or tooth 93 without engaging the same. Another set of teeth a1 is arranged to be engaged by the pin 76 and set of teeth 95 is arranged to be engaged only by the pin 7 5 of the day wheel. The projections or teeth 93, 91, 95 of the month wheel are arranged in proper order depending upon the months which they represent so that the month wheel may be actuated when the day wheel has been advanced through a number of teeth corresponding to the days of the month.

The month wheel is turned through the distance of one tooth by any one of the pins U 75, 76 77, 78, when the tooth engages a corresponding month tooth or projection of the month wheel, causing the month wheel 80 to turn the gear or toothed wheel 85 through the distance of one tooth. This is accomplished by so proportioning the members that the detent 67 will be moved out of the space between two of the teeth of the wheel 85, thus permitting the wheel 85 to turn through the distance of one tooth.

. This causes the detent to be moved into the position in which the tooth thereof will be moved out of engagement with the ratchet teeth of the day wheel d2, as shown in Fig. 6. When in this position a tooth 98 of the detent 67 will engage a detent or latch 100, thus holding the pawl 67 out of engagement with the teeth of the month wheel and permitting the spring 63 to return the month wheel to its starting position. The detent 100 shown in the drawings is mounted on a pin 101 secured on an arm or projection 102 of the frame of the clock, and is yieldingly pressed by means of a spring 103 against the pawl 67 so as to engage the tooth 98 thereof when the detent is raised out of engagement with the day wheel 12. The detent or latch 100 is preferably provided with an outwardly extending arm 104 which enters into a slot 105 in the projection or arm 102 of the frame which limits the movement of' the pawl about its pivot. The spring connection between the month wheel 80 and the toothed or gear wheel 85 makes it possible for the month wheel to be moved back by the pins or projections on the day wheel when the same is returning to its initial position without interfering with the gear 85. After the pins or projections of the day wheel have passed the month wheel the spring 84 returns the month wheel to its operative positions in which the stops 87 and 88 are in engagement.

he detent 100 is provided at its other end with a slotted or bifurcated portion 110 which extends into operative relation to a stop pin 111 secured on the day wheel 42 and into which the stop pin of the day wheel is adapted to enter when the day wheel returns to its initial position. The detent 100 thus acts as a stop to hold the day wheel in itsinitial position when the pawl 67 is out of engagement therewith. V The pin 111 engaging the latch 100 swings the same about its pivot to a sufiicient extent to withdraw the latch from engagement with the tooth 98 of the pawl 67, thus permitting the pawl to again move into engagement with the teeth of the day wheel 42.

In order to prevent the momentum of the day wheel 12 from causing the same to rebound after striking the detent 100 a spring or retaining member 114 is preferably provided having a notched or bent portion 115 into which the arm 10% of the detent 100 is adapted to enter when the same has been moved to the limit of its movement by the pin 111 and which yieldingly holds the pawl against movement out of this position and vthus prevents rebound of the day wheel, F 7. Other means for returning the day wheel to its starting position at the end of each month may be provided.

The gear or toothed wheel preferably meshes with a pinion 120 mounted on a pivot 121 suitably journaled in the clock frame and provided at'its outer end with a hand or pointer 122 which indicates the months on the dial of the clock, the hand 122 being adapted to complete a revolution once in a year and the month wheel 80 is. adapted to complete a revolution once in four years in order to enable the clock to correctly register the 29th day of February once every four years.

In theoperation of the clock, the driving gear 35 causes the wheel or plate 4:5 to revolve, thus causing the spring tooth 16 to be moved about its pivot d7 by means of the Geneva mechanism shown. when the spring tooth is extended out vardly from the axis d1 of the wheel 45, the tooth will engage the day wheel, causing the same to advance through the distance of one tooth. The pawl (57 holds the day wheel in advanced position until one or another of the pins 75, 76, 7'7 or T8 engage the corresponding tooth or projection of the month wheel and move the month wheel about its pivot through the are of one tooth. This movement of the month wheel causes the gear 85 to move the pawl 67 out of engagement with the day wheel, the detent 100 holding the pawl in this position. The day wheel is then returned to the initial position by the spring (53 and in returning to its starting position, the day wheel engages the detent 100, releasing the pawl S'Twhich again moves into engagement with the day wheel 5 2.

A clock of modified and somewhat simplified construction is shown in Figs. 19 and :20 in which a month wheel 130 is employed which is similar in construct-ion to the month wheel 80 but which has only twelveteeth corresponding to twelve months of the year andw iich consequently does not provic e for an extra day in February in every fourth year. The month wheel 130 is connected in the same manner as hereinbetore described to a toothed wheel 181 mounted to rotate about the same axis as the wheel 130 and engaging a tooth or pin 132 of a pawl 133 corresponding to the pawl 67. In other respects this mechanism corresponds substantially with that shown in Figs. 1 to 18.
